What size are the transmission crossmember bolts for 1977 Porsche 911S
Anybody know what size the transmission crossmember bolts are for a 1977 Porsche 911S.
Are there any spacers that are supposed to be installed with the bolts and what size are they? Thanks for any and all help! |

The bolt thread size is 1.5 - this is the same size as 450 Mercedes wheel bolts & maybe 911 studs too???
I know this because I used a MB bolt to make a thread chaser by dremeling a slot in it. Be VERY carefull with the crossmember hole as the mounting threads in the chassis strip real easy. |
